The formula to calculate the wire size for a three-phase AC circuit is slightly different: A(m²) = √3 ×ρ(Ω·m)× L(m)× I(A) / V(V) The minimum cross-sectional area A for a wire in square meters is equal to the product of the square root of three, the conductor...

If the cross sectional area of the wire is 1mm2, then the young's modulus of the material of the wire is (a). 2×1011Nm−2 (b). 2×1010Nm−2 (c). 12×1011Nm−2 (d). none of these View Solution Calculate the force required to incrase the length of wire of cross...
One 'mil' is one thousandth of an inch. A wire with a cross sectional area of 1 circular mil has a diameter of .001". If we need to calculate the circular mils for a 10g wire, we simply square the diameter in mils. Since the 10g wire has an approximate diameter of .1" or 100...
of the wire diameter, and every 3 gauge decrease doubles the wire cross sectional area. Similar to dB in signal and power levels. An approximate but accurate enough form of this formula contributed by Mario Rodriguez is D = .460 * (57/64)(awg +3)or D = .460 * (0.890625)(awg +3)...
According to the resistance law (R = ρL/A, where R is the resistance, ρ is the resistivity, L is the length, and A is the cross-sectional area), the resistivity can be calculated when the length and cross-sectional area of the annealed wire are known, thereby evaluating its ...
Learn various ways to determine the cross-sectional area of a wire and make sure that the cables can withstand the current.
This means that in American wire gage every 6 gauge decrease gives a doubling of the wire diameter, and every 3 gauge decrease doubles the wire cross sectional area. Similar to dB in signal and power levels. An approximate but accurate enough form of this formula contributed by Mario ...
